Abstract: In this wing, three individual wings which receive their shape due to the air flowing onto them are connected to form a unit and are fixed in their relative position by cords (Figure 3). For the purpose of increasing lift, the two lower wings (2,3) are arranged as tandem wings of large spread with an air jet gap (6). An upper wing (1), attached above it, fixes the position of the tandem arrangement and, with it, the shape and spacing of the air jet gap. Additionally, the upper wing is constructed with safety in mind. Its span is less, the spread is substantially smaller, the inlet openings (8) are larger and are mounted further forwards than in the case of the two lower wings. For aerodynamic reasons, the upper wing and the rear one of the two lower wings have a greater incidence (4). The suspension of the weight to be borne, e.g. pilot, motor car, motor cycle, motor boat or the like, takes place as with conventional gliding chutes via top cords (11,12) and a harness (13). The control takes place likewise as with normal gliding chutes via control cords (14) which lead to the right and left rear edges of the 3-section wing. <IMAGE>

Abstract: In previously known devices for stabilising grass paths, intersecting webs have been used and the free passages formed between the latter have been filled with earth. Such a design, however, has the disadvantage that the erection of the webs is extremely labour-intensive, and that the grass paths so stabilised, when travelled by utility vehicles or subjected to the pressure of the earth on embankments, are not sufficiently stable. The object of the invention is to provide a device for stabilising grass paths which ensures adequate stability combined with a low level of effort. This object is achieved in that a device for stabilising grass paths is provided which is designed as a one-piece turf grid panel (1), which can be connected by means of connecting elements to adjacent turf grid panels (1) which can be positioned, the connecting elements of adjoining turf grid panels (1) preferably being hooking elements (7) which engage into each other in pairs. <IMAGE>

Abstract: An improved lid mechanism for a web feed device, particularly device for feeding perforated paper webs in printers, copiers and the like, and more particularly a tractor with an improved lid mechanism, wherein pins on which the lid (10) is pivotally mounted for movement between open and closed position are unloaded (do not have any force or bias applied thereto) when the lid is in its open and closed position. The lid (10), when closed, covers the paper and is then spaced from the surface (34,36) of a frame along which the paper is fed by a pin drive such as a belt (26) having pins (28) which extend into perforations of the paper (30). A depending leg (48) of the lid has a block (60) with surfaces (70,72) disposed at an angle (72) to each other. These surfaces extend from a corner (74) of the block. One of these surfaces (70) is preferably perpendicular to the surface (38) of the lid which defines the gap. The other of these surfaces (72) defines the position of the lid in its open position. These surfaces bear against the outer wall (56) of a side plate (16) of the frame of the device (the tractor) and are biased thereagainst by a flat spring (82) mounted on the side plate (16). This spring (82) bears against surfaces of said block opposite to the surfaces which bear against the outer   side wall. The location of the lower surface (38) of the lid and the size of the gap (40) is defined by a pin and slot (76) hinge arrangement. The slot is longer (76) than the stroke of the pin which is executed as the lid moves between its open and closed position. Accordingly in both the open and closed position the block is under compression and the pin is unloaded. The lid may be molded and an integral body of plastic. The use of steel pins may be avoided. The location of the lid and the size of the gap is accurately defined since dynamic factors such as material strength, bending deflections and part homogeneity do not affect the accuracy of the lid position; the position being dependent only on the static dimensions of the block, the pin and the groove.

The direction of rotation about the first gimbal axis is periodically reversed. A second gimbal (18) is provided for rotating the triad of gyroscopes and accelerometers at a predetermined control angular rate. The second gimbal axis (D2) is directed along an axis orthogonal to the plane described above whose orientation is fixed in inertial space (as, for example, the earth's polar axis if this plane is parallel to the equatorial plane of the earth). The direction of rotation about the second gimbal axis is periodically reversed.

Abstract: A co-axial laser tube structure (11) of the kind used in a flowing gas laser has an inner axially extending tube (13) for confining the flowing gas in a discharge region, a single pin cathode (19) mounted adjacent the hot end of the inner tube (13), a single pin anode (21) mounted intermediate the cool end and the hot end of the inner tube (13), a gas entrance orifice (23) for permitting gas to flow from the exterior tube (13) into the interior of the tube at the location of the anode electrode means (21), and an outer tube (25) which is separate from and which extends co-axially with the inner tube (13). The outer tube (25) is made of plastic and conducts flowing gas along the outside of the inner tube (13) from the cool end to the gas entrance orifice (23). The co-axial laser tube structure includes tube installation and mounting means (15, 17) effective to permit installation and/or replacement of the inner (13) and outer (25) tubes without the need for subsequent adjustment or bore registration of the tubes. The inner surface of the inner tube (13) is frosted to minimize parasitic modes which could be produced by diffracted light impinging on the inside surface of the inner tube at a grazing angle and also for decreasing the boundary layer of thickness to improve turbulence in the gas flow between the anode (21) and the cathode (19). The installation and mounting means (15, 17) include shaft seals (43), chamfers (43, 57) and related O-rings (51, 55) which are effective to hold the co-axial laser tube structure in registration with the bore without over contraint. The centering ring (31) at the hot end of the inner tube (13) has an aperature which shadows the glass tube from any diffracted light of the laser beam. This centering ring (31) has an inner gas flow opening (29) which is curved with a sufficiently large radius to eliminate any turbulence in the gas flow through the opening (29). A downstream diffuser (29A) recovers some velocity head of the gas flowing through the centering ring (31).
